A.V.
If she's not ready to wean, then she's not ready. If you don't mind, I wouldn't worry about it, but I'd teach her manners. My DD learned not to grab at my shirt in public, for example. Many people also teach their children a code word or nickname (my DD signed so we used the signs for Mommy and Milk together). I have found with my DD that a little maturity from her and a little encouragement from me has fairly gracefully brought us to just a few minutes at night and no longer every night. As she gets older, ask her if she wants a cuddle, a book, a snack, a drink...she could be seeking a lot of things from that time with you.
